I have a 94 chevy cavalier. and it wont start. the coil is fine and so is the spark plugs. and it does turn over when i crank it... i would pump the gas a couple of times and it would seem to try and start but just not start.

Chevy 2500HD No Start No Spark No Fuel Cranks OK
Testing !!!

Tyhe first thing you shd always do on any car with starting problems is to check the spark on the plugs to localize the problem to either fuel or ignition problem. If u have an old spark plug lying around, remove one spark plug wire and attach it to the plug and lay it against the block. If it fires, when the engine turns, then it will most likely be fuel problem.
If it turns out to be fuel problem, you can prove it by using starting fluid carefully into the breather area.

Check your fuel pump. It may have died. One way to check is to see if you smell gas at the tail pipe after trying to start it. If you don't, that is a good indicator that the fuel pump ma have died or your fuel filter is clogged.

If you have no spark try the ignition module, it controls the spark and if you don't have any and the coil is new its the only other option short of wiring or ecu!!

does it produce fire does the gas pressure rise does the crank sensor and cam sensor work

What size engine? Sounds like crank sensor or ignition module.

check fuel pressure to the fuel pump

Spray aerosol carb cleaner into the throttle body while an assistant tries to start the engine. If it runs for a few seconds then quits, you are not getting fuel into the engine. Check the fuses. You might have blown the fuse for the fuel injectors (possible if you removed any of the injector harnesses) or the fuel pump relay.

Need to actually,physically,check spark.Pull a plug wire off the plug,insert a medium size phillips head screwdriver into the spark plug wire boot,making sure it clicks in and engages.Lay the screwdriver's metal shank about a 1/4" from a metallic ground source (not the fuel line).Have someone crank the car over while you are looking for an arc between the screwdriver and ground.No arc...no spark...cheap easy way to check for spark and eliminate or not,the ignition system.

check to see if you can hear the fuel pump running.just cycle the key to the on position but dont turn over the motor you should hear a humming sound come from the fuel tank.if no sound check your fuses if all ok could be a bad fuel pump
or check to see if you have spark if no spak then it could be the module inside your distributor cap.it also controls the fuel pump.
